title: Standardization of laparoscopic left hemicolectomy: a single-center experience of 484 cases.
abstract: OBJECTIVE
  Laparoscopic surgery has become recognized as an established technique for colon diseases and many different surgical techniques have been described. The aim of our study is to show the results of a single institution where a standardized operative and perioperative procedure for laparoscopic left hemicolectomy (LLH) has been used.
  
  
  METHODS
  Between January 2005 and April 2011, 484 patients underwent LLH for colon diseases. Data collected included age, indication for surgery, ASA class, body mass index, operating time, intra and post-operative complications, conversion rate, length of hospital stay, tumor stage, number of lymph nodes harvested, mortality, and a 30-day readmission rate.
  
  
  RESULTS
  We found 299 cancer, 29 large dysplastic polyps and 156 complicated diverticular diseases. Average operation time was 120 minutes. The average hospital stay was 5.7 days. In the cancer group, the average number of lymph nodes harvested was 12.7. The intraoperative and early postoperative complications were 3.3% and 10.7 % respectively. The conversion rate was 3.7%. The 30-day readmission rate was 3%. The 30-day mortality rate was 0.4%. CONCLUSION. The standardization of the LLH technique might reduce the technical difficulties and complications. Its potential benefits include the standardization of surgical instrument sets, the definition of benchmarks for conversion before making any inappropriate investment in time and equipment, low rates of complications and readmission rate.
